Oracle Import Export compatibility matrix
提问by CoolMagma
Is there an official matrix that clearly explain how export dump format done with a specific version, is or not compatible with all others?
是否有一个官方矩阵清楚地解释了如何使用特定版本完成导出转储格式，是否与所有其他版本兼容？
I mean to fill this grid:
我的意思是填充这个网格：
Exp done with version: | 7 | 8i | 9i | 10g | 11g
Is compatible with Imp 7 |yes | no | no | no | no
8i|yes |yes | no | no | no
9i|yes |yes |yes | no | no
10g|yes |yes |yes | yes | no
11g|yes |yes |yes | yes | yes
I known there are many specific thinks between YES and NO.
我知道在 YES 和 NO 之间有很多具体的想法。
I also need an Oracle official clear sentence like this: "Oracle will allways support back-ward compatibility for import any old export dump format"
我还需要一个像这样的 Oracle 官方明确语句：“Oracle 将始终支持向后兼容导入任何旧的导出转储格式”
please help me

I doubt that Oracle has ever made a commitment that something will always be supported. For example, the regular export command is being desupported in 11g in favor of the DataPump version, which uses a different file format. The old export utility will be around for a while, but I wouldn't assume that 10 releases down the line Oracle would even be shipping versions of the non-DataPump export and import utilities.
我怀疑 Oracle 是否曾承诺过某些东西将永远得到支持。例如，常规导出命令在 11g 中被取消支持，取而代之的是使用不同文件格式的 DataPump 版本。旧的导出实用程序将存在一段时间，但我不认为 Oracle 的 10 个版本甚至会发布非 DataPump 导出和导入实用程序的版本。
